HELOC requirements and eligibility: credit score, equity, DTI and the documents you need

8 min read · LenderMatch Learn

To qualify for a HELOC, most lenders check four eligibility requirements: a credit score at or above their minimum (published minimums we found run from 600 to 660), enough equity that all loans on the home stay at or below about 80% to 85% of its value, a debt-to-income ratio usually under 43% (some lenders allow 50%), and steady income you can document. You will also need homeowners insurance and a valuation of the home.

No federal rule sets one checklist for every HELOC, so each lender draws these lines in a different place. Below are the published numbers from real lenders, a worked example that shows how they combine, the documents to gather, and what happens in underwriting. Because the cutoffs differ, one lender's "no" can be another lender's "yes," which is why comparing several lenders can change the answer.

What are the requirements for a HELOC?

Here is what lenders publish, with an example of each:

Why the range? The federal ability-to-repay rule that governs most mortgages (Regulation Z, 12 CFR 1026.43) excludes home equity lines of credit. So the minimums above are lender policy, and they change. Check a lender's current page before you apply.

What credit score do you need for a HELOC?

There is no single legal minimum. One national online lender says most lenders require at least 620, while its own minimum may start at 600. Another lender's lowest published tier starts at 640, and a large national bank says you'll need a FICO score of 660 or higher.

Your score does more than open the door. Many lenders tie your borrowing limit to it. One lender's published home equity matrix (release date September 8, 2026) shows the pattern for a primary home:

• 740 and up: up to 90% combined loan-to-value
• 680 to 739: up to 90%
• 660 to 679: up to 80%
• 640 to 659: up to 70%

Lenders also read the details behind the score. The same matrix uses the lowest middle score among all borrowers, allows at most one 30-day late mortgage payment in 24 months (none in the last six), and asks for either three credit accounts with recent history or a mortgage paid as agreed for 36 months. If your score is near the cutoff, see a HELOC with a 620 credit score or getting a HELOC with bad credit.

How much equity do you need for a HELOC?

Lenders measure equity through combined loan-to-value (CLTV): every loan on the home, including the new line, divided by the home's value. One national online lender says most lenders prefer a CLTV of 80% to 85% or lower, and most require you to keep at least 15% to 20% equity after the line opens.

The formula for your maximum line is home value × the lender's CLTV limit − what you owe. On a $400,000 home with a $250,000 mortgage, an 80% limit allows up to $70,000. Our guide on how much equity you can borrow works through more examples.

One state sets its own ceiling. In Texas, the state constitution caps all debt on a homestead at 80% of its fair market value when a home equity loan is made, at every lender. Our Texas HELOC guide covers that rule and the 12-day wait.

HELOC debt-to-income ratio requirements

The CFPB defines your debt-to-income ratio (DTI) as "all your monthly debt payments divided by your gross monthly income." Lenders count the payment on the new line too, so your DTI after the HELOC is what matters.

• One national online lender says most lenders prefer a DTI below 43%, though some require 36% or lower, and the cutoff can vary with your score and equity.
• Another lender lists a maximum DTI of 50% on its home equity matrix.

Gross income is your income before taxes. In the CFPB's own example, a $1,500 mortgage, a $100 auto loan and $400 of other debt payments add up to $2,000 a month; on $6,000 of gross monthly income, that is a 33% DTI.

Worked example: does this homeowner qualify?

Say your home is worth $425,000 and you owe $250,000. You earn $8,000 a month before taxes and pay $2,600 a month in debts ($2,000 mortgage, $450 car, $150 in card minimums). You want a $60,000 line.

• CLTV with the line: ($250,000 + $60,000) ÷ $425,000 = 72.9%. That's under an 80% limit, which would allow up to $90,000.
• DTI today: $2,600 ÷ $8,000 = 32.5%.
• DTI with the line: at an example 8.00% rate (prime, 7.00% as of October 20, 2026, plus a 1.00% margin), interest on $60,000 is $400 a month. Payments become $3,000, or 37.5% of income.

On these numbers you would be under a 43% DTI limit and well inside 80% CLTV. Now change one thing: your score is 650. At that lender's published 640 to 659 tier, the CLTV limit drops to 70%, so the most that lender could offer is $425,000 × 70% − $250,000 = $47,500. Same house, same income, $12,500 less line. A lender that uses a higher, fully amortized payment to qualify you would also show a higher DTI than this interest-only example.

Home equity line of credit documents needed

One large bank publishes one of the most complete checklists. Other lenders ask for similar items:

• Identity: a government-issued photo ID, your Social Security number, and your addresses and employers for the past two years.
• Income, if you're employed: pay stubs covering the last 30 days and W-2s for the last two years. A large national bank also lists pay stubs, tax returns and W-2s.
• Income, if you're self-employed: two years of signed personal tax returns with all schedules. If you own 25% or more of a business, that first bank also asks for two years of business returns and a year-to-date profit and loss statement and balance sheet.
• Retirement or other income: a Social Security or pension award letter, investment statements, or leases for rental income. For a HELOC, that first bank accepts two months of deposit history in place of the Social Security letter.
• The property: your homeowners insurance declaration page, your latest mortgage statement, a property tax bill if taxes aren't escrowed, and flood insurance if the home is in a flood zone.

HELOC underwriting: what happens after you apply

1. Application and credit check. The lender you choose checks your credit with your permission.
2. Income and debt review. The lender verifies your documents and calculates your DTI.
3. Home valuation. This can be a full appraisal, a drive-by or an automated valuation. One lender's published matrix allows an automated valuation for lines under $250,000. If you've owned the home less than six months, it uses the lower of the appraised value and what you paid, and it won't lend on a home listed for sale in the past 120 days.
4. Approval and closing. The CFPB notes that some lenders charge an appraisal fee and an application fee that "might not be refunded if you are turned down," while others waive them.
5. Three days to cancel. Under federal law, you can cancel a new HELOC on your home within the first three days after the account is opened, and the lender must return the fees you paid (CFPB).

Requirements don't end at closing. The CFPB says HELOCs generally let the lender freeze or reduce your line if your home's value falls or your finances get worse. It also notes that renting your home out may be prohibited under the terms of your line.

How to meet HELOC requirements if you're close

• Ask for a smaller line. It lowers your CLTV and the payment counted in your DTI.
• Pay down a small debt. Clearing a $450 car payment in the example above would cut the DTI by more than five points.
• Check your credit reports for errors. The CFPB's HELOC booklet suggests looking for errors that might have caused a downgrade in your credit.
• Compare lenders in a short window. Score tiers, CLTV limits and DTI caps all differ. Our guide on whether rate shopping hurts your credit explains how inquiries are counted.

Frequently asked questions

What credit score do you need for a HELOC?

Each lender sets its own minimum. Published minimums we checked run from 600 (a national online lender, which says most lenders require 620) to 640 and 660 at other lenders. A higher score usually brings a higher borrowing limit and a lower rate.

What is the maximum debt-to-income ratio for a HELOC?

It depends on the lender. One national online lender says most lenders prefer a DTI below 43%, and some require 36% or lower. One lender's published home equity guidelines allow up to 50%. Your DTI is all your monthly debt payments, including the new line, divided by your gross monthly income.

How much equity do you need for a HELOC?

Most lenders want you to keep at least 15% to 20% of your home's value as equity after the line opens, which means all loans on the home stay at or below 80% to 85% of its value. Some lenders go to 90% for borrowers with strong credit. In Texas, state law caps all home equity borrowing at 80%.

What documents do you need for a HELOC?

Usually a photo ID, recent pay stubs and two years of W-2s (or two years of tax returns if you are self-employed), your latest mortgage statement, your homeowners insurance declaration page and, if your taxes are not escrowed, your property tax bill. Lenders may ask for more.

Do you need an appraisal for a HELOC?

You need some kind of home valuation, but not always a full appraisal. Some lenders accept an automated valuation or a drive-by appraisal on smaller lines. One lender's published guidelines, for example, allow an automated valuation for lines under $250,000.

Does LenderMatch check my credit?

No. LenderMatch never pulls your credit. A lender you choose may check it, with your permission, when you apply.
